How To Change The Color Of Your Hydrangea

The pH level of your soil dictates what color your hydrangea will be.  Here’s the cool part – you can change the pH level of your soil. 

First test the pH level of your soil to determine if you have alkaline or acidic soil.  Alkaline soil (7.0 or higher) creates pink hydrangeas blooms and Acidic soil (lower than 6.0) creates blue blooms.

Add lime to the soil to create an Alkaline soil condition and pink blooms.

Add aluminum sulfate to the soil to create an Acid soil condition and blue blooms.
